Amazon began with books. Netflix began with DVDs. Nintendo began with playing cards. Instagram began as something called Burbn.
Today, these names are attached to businesses that look very different from their earliest versions. That difference matters because building a company rarely means taking an idea from a notebook and executing it exactly as planned. The original idea can provide the starting point, but customers, technology, competition and experience can change what the business eventually becomes.
Amazon is a clear example.
When Jeff Bezos founded Amazon in 1994, the idea was to build an online bookstore with a selection that a physical shop could not match. Amazon opened its virtual doors in July 1995, selling books online. Its early communications described the company as an online bookseller, and its initial ambition was to use the internet to offer an unusually large selection of books.
The company did not remain there. Within a few years, Amazon had moved into music, videos, toys, electronics and other categories. By 1999, it was describing itself as a place where customers could find and discover almost anything they wanted to buy online.
The important part of the Amazon story is not that Bezos had a grand plan to sell everything from the beginning. He started with a specific category that made sense for the internet and expanded from there.
A starting point does not have to define the final size of the business.
That also offers a useful lesson for anyone sitting on an idea and waiting for it to become perfect before taking the first step. Amazon did not need to know everything it would eventually become before it launched. The initial idea was specific enough to test, and the business grew as Bezos and his team learned what the market could support.
You do not need the finished idea to begin. You need an idea that is developed enough to test.
Thinking can improve an idea, but putting it into the market produces information that thinking alone cannot provide. Customers can reveal what they value, what they ignore and what needs to change.
But starting is only part of the process. What happens when the conditions around the business change?
Netflix followed a different path.
When Netflix launched its online DVD rental store in 1998, customers could rent DVDs through the internet and receive them by post. The service was built around the technology and consumer behaviour of its time.
That business eventually became something else.
As broadband internet improved, Netflix introduced streaming in 2007. The company later moved into original programming, beginning with House of Cards in 2013. In 2023, Netflix sent its final DVD, bringing an end to a 25-year chapter that had provided the foundation for its next stage.
Netflix’s story shows that an idea can be right for one period and still need to change as the market changes. A founder who remains committed to the original business model simply because it worked at the beginning can miss the opportunity created by new technology or changing customer behaviour.
The business you start is not necessarily the business you will need to keep building.
Nintendo’s history stretches even further.
In 1889, Fusajiro Yamauchi began a small business manufacturing Hanafuda playing cards in Kyoto, Japan. Nintendo eventually moved into other forms of entertainment and began manufacturing games alongside playing cards in 1963. By 1978, it had entered the video-game business, and the company later became one of the world’s best-known names in gaming.
There is a useful distinction here. Nintendo did not abandon the idea of entertainment; it changed the form through which it delivered it.
For founders, that distinction matters. Sometimes the enduring idea is not the original product. It may be the problem the company wants to solve, the experience it wants to create or the market it wants to serve.
Nintendo’s history shows that a company does not have to remain confined to the business it first entered.
The product can change while the purpose behind the business remains.
Instagram offers perhaps the clearest example of an idea being reshaped by users.
Before Instagram, Kevin Systrom and Mike Krieger were working on Burbn, a location-based social app that allowed users to check in, make plans, share photos and interact in several ways. After watching how people used the product, the founders noticed that photo sharing was attracting the strongest interest. They decided to strip the product down and focus on photographs.
The change was significant. They had spent about a year working on Burbn, then threw most of it away and built the much simpler product that became Instagram.
The lesson is straightforward: an idea can become stronger when you remove what is unnecessary and focus on what works.
For founders, that can be uncomfortable. Time, money and effort create an attachment to what has already been built. But the work invested in an idea does not automatically make the idea worth keeping in its current form.
Building something is not a reason to keep building the wrong thing.
Amazon, Netflix, Nintendo and Instagram took very different paths, but their histories reveal the same principle: successful businesses are often shaped through the process of building them.
Amazon began with books and expanded. Netflix began with DVDs and moved into streaming. Nintendo began with playing cards and eventually became a gaming company. Instagram began as Burbn before its founders focused on the feature users valued most.
For someone with an idea today, that means the first version does not have to answer every question. It needs to be strong enough to test.
Waiting until an idea feels completely developed can keep it permanently in your head. Starting gives you evidence. Customers respond. Markets reveal opportunities. Problems become clearer. Some assumptions survive; others have to be discarded.
The point is not to change direction every time something becomes difficult. It is to distinguish between persistence with purpose and attachment to an idea simply because it was the original one.
An idea is a starting point, not a finished product. Build it, learn from what happens, and give yourself permission to improve what you started.
